How to fix Compass data missing on Simrad Autopilot System?
If your Simrad Autopilot System shows 'Compass data missing', and multiple compasses are connected, use the User Setup2/Source select menu to select a different compass. If no compass is available, make a source update. Check connections and replace the compass PCB, ensuring you do not cut cables and use the screw terminals inside.
What does ACXX high temp. mean on Simrad Autopilot System?
If your Simrad Autopilot System displays 'ACXX high temp.', it indicates excessive temperature in the Autopilot Computer (over 75°C), possibly due to long-term overload. Switch off the autopilot. Check for backload in the drive unit/steering system, and ensure that the autopilot computer specifications match the drive unit.
What causes Rudder feedback failure on Simrad Autopilot System?
If your Simrad Autopilot System indicates 'Rudder feedback failure', the rudder feedback signal is missing or erratic, causing the autopilot to operate on simulated feedback. Check all connections and the alignment as per the installation instructions. If the issue continues, replace the rudder feedback unit.
What does ACXX current overload mean on Simrad Autopilot System?
If your Simrad Autopilot System displays 'ACXX current overload', the drive unit shut down due to an excessive load or a short circuit. Check the drive unit and its installation, manual steering, and the rudder. Disconnect the drive unit. If the fault is still present, replace the Autopilot Computer Power PCB.
What to do if my Simrad Autopilot System shows 'ACXX high temp'?
If your Simrad Autopilot System indicates 'ACXX high temp', this means there's excessive temperature inside the Autopilot Computer. You should switch off the autopilot.
What to do if Simrad Autopilot System shows Rudder response failure?
If your Simrad Autopilot System shows 'Rudder response failure', it means there is no response to rudder command. Check all connections, the Rudder FB transmission link, and the drive unit motor/brushes. If the problem persists, replace the Autopilot Computer Power PCB.
Why is my Simrad Autopilot System boat off course?
If your Simrad Autopilot System boat is off course, it may be due to extreme weather conditions or too slow speed. Check the steering parameters (Rudder, Autotrim, Seastate filter), increase the Rudder value, and increase boat speed if possible. If not, steer by hand.
What to do if Simrad Autopilot System displays NAV. data failure?
If your Simrad Autopilot System displays 'NAV. data failure', it indicates missing or invalid NAV data. First, check the Nav. Receiver/GPS setup. For further assistance, consult Service menu Chapter 4.9.
How to fix 'Failure active Control Unit' on Simrad Autopilot System?
If your Simrad Autopilot System indicates 'Failure active Control Unit', and the active control unit goes silent, here's how to troubleshoot: 1. Press the STBY button on an "Inactive" unit to reset. 2. Check/repair Robnet2 cable. 3. Replace the control unit PCB.
What to do if Simrad AP25 Autopilot System displays 'Shallow water'?
If your Simrad Autopilot System (specifically AP25) displays 'Shallow water', it indicates that the depth is inside the set limit or outside the range, or depth data is missing. To resolve this: 1. Carefully observe the actual depth. 2. Adjust the alarm limit if not hazardous. 3. Steer to a safe depth; the alarm will reset automatically. 4. Turn off the shallow alarm if depth data is missing.
